Ingredients
Directions
Make the syrup
Dissolve sugar in water in a preserving kettle.
Add egg white and beat well.
Heat mixture, stirring with a wooden spoon until it begins to swell and boil.
Add a little cold water and let it boil again.
Remove scum and repeat until syrup is clear and pours like oil from the spoon.
Cook the fruit
For each pound of fruit, use ¾ pound of sugar.
Boil fruit in a porcelain‑lined or granite‑ware dish.
To make dry preserves, drain fruit from syrup and dry in a moderate oven, turning every 6‑8 hours and sifting powdered sugar over them each time.

What each ingredient does
- White sugar
- Sweetens the preserve and, once boiled to a syrup, helps set the fruit and preserve it.
- Egg white
- Binds to impurities as it heats so they rise as scum that can be skimmed off, clarifying the syrup.
- Fruit
- Provides the flavour and body of the preserve, cooked in the sugar syrup.
The step that matters
Remove scum and repeat until syrup is clear. Skimming the scum that rises as the egg white coagulates clarifies the syrup. Leftover scum makes the preserve cloudy and can spoil its flavour, so the boiling and skimming should be repeated until the syrup runs clear.
